Any establishment that holds a “Class B” liquor license may sell wine
for off-premises consumption in the original container in any quantity
regardless of whether the municipality has adopted an ordinance allowing
carryout liquor sales. Wis. Stat. Sec. 125.51(3)(b).

Any establishment holding a “Class B” liquor license may sell intoxicating liquor to consumers for off premises consumption only if
the municipality has enacted an ordinance under Wis. Stat. Sec.
125.51(3)(b) allowing such sales. Sales of liquor for off-premises
consumption cannot exceed four liters at any one time.

Finally, in restaurants, a “Class B” liquor or a “Class C” wine license
authorizes the sale of wine in an opened original bottle to a person
that orders food for consumption on and off the premises where sold in a
quantity not to exceed one bottle. Wis. Stat. Sec. 125.51(3r). The
unfinished partially consumed bottle can be taken off the licensed
premises if the licensee securely reinserts the cork into the bottle so
that the top of the bottle and the cork is reinserted at a time other
than between 12:00 midnight and 6:00 a.m.
